Flooding may isolate Wanaaring

Residents in the far north-west New South Wales town of Wanaaring are warned they could be cut off by flooding for several weeks.

Floodwaters impacting on southern Queensland are expected to arrive in the town next Friday.

The weather bureau predicts the Paroo River will peak at four metres at Wanaaring which is major flood level.

The acting controller for the far west division of the State Emergency Service (SES), Graeme Craig, says the town's 70 residents and outlying landholders could be isolated by the rising waters.

"To the actual residents of Wanaaring there won't actually be an impact to their premises. However, what will actually occur is they may become isolated for up to four weeks, so access north, east, south and west will become cut by floodwater," he said.

Mr Craig says the flooding is expected to be similar to that experienced four years ago.

He says residents should be prepared.

"It's a good idea at this stage to take the opportunity before the floodwaters hit to actually stock yourselves up with essential items," he said.

"The SES will be working on resupply for ... when the water actually does hit, we will make sure the community is looked after and capable of maintaining itself while the town remains isolated."

Villages in the Bourke Shire are not expected to be threatened by floodwaters heading downstream from Queensland in the Warrego and Paroo rivers.

The general manager of the Bourke Shire Council, Geoff Wise, says the water will do more good than harm by benefiting pasture growth on the floodplain.

"We're monitoring very closely the potential risk of any of the communities in the Bourke Shire such as Enngonia and Fordes Bridge on the Warrego and then the Warrego after it hits the Darling, well Louth is immediately downstream, but we're very confident the flood peaks are not going to threaten any of those villages," he said.
